如何从Java程序执行命令

Question

I need to execute this command to stop selenium server.

wmic path win32_process Where "CommandLine Like '%selenium-server%'"  Call Terminate

from my java program. I tried

Runtime.getRuntime().exec("command as a single string escaped")

and

Runtime.getRuntime().exec(String[])

but it is not getting executed. When I execute the same command from cmd it is working fine. Can someone please help.

Answer 1

使用ProcessBuilder更好地转义/处理空格。

Answer 2

You can try to use this one :

public Process exec(String[] cmdarray, String[] envp, File dir) 
  throws IOException   

Executes the specified command and arguments in a separate process with the specified environment and working directory.

then wait for the process to end using the process.waitFor() methode.
